    Caterpillar electrification field trials: haul truck design lessons for mine engineers

    February 26, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Caterpillar Product Support Manager Jeremy Byrd details how field trials of battery‑electric and trolley‑assist haul trucks are shaping the company’s electrification support model for large open pits. Recurrent customer questions centre on duty‑cycle modelling, charger placement around shovel faces and dumps, grid stability for multi‑megawatt fast chargers, and integration with existing diesel fleets. Byrd points to early projects using Cat® MineStar™ data, real‑time energy monitoring and iterative route redesign as critical for sizing on‑board energy storage and planning phased infrastructure roll‑outs.

    Technical Brief

    • For other mines, the key implication is reduced “first‑of‑kind” risk when scaling similar electrification programmes.

    Our Take

    Caterpillar’s Electrification + Energy Solutions Division is one of only a few OEM-focused groups that appear repeatedly in our mining ‘Product’ and ‘Sustainability’ coverage, signalling that miners are likely to see integrated offerings (machines, charging, and site power) rather than piecemeal electrification components.

    Within the 2,000+ tag-matched pieces on projects and sustainability, most OEM stories still centre on diesel efficiency or hybrids, so a dedicated electrification division at Caterpillar suggests major fleets may now be planning for full-electric mine phases rather than incremental retrofits.

    Because this article sits in our mining projects stream without specific mine names or countries, it points to Caterpillar targeting platform-level solutions that can be standardised across regions, which can shorten deployment timelines but may require miners to adapt site layouts and power contracts to fit the OEM’s preferred architecture.

    Lynas Rare Earths profit surge: mine expansion and processing insights for engineers

    Lynas Rare Earths has reported record profits on the back of surging global demand for rare earth oxides used in permanent magnets for EV motors and wind turbines, enabling accelerated expansion of its Mt Weld mine and downstream processing. CEO Amanda Lacaze is pushing ahead with capacity growth at the Western Australian concentrator and the new Kalgoorlie cracking and leaching plant, designed to reduce reliance on offshore processing. For mine planners and process engineers, the move signals sustained demand for high-grade monazite-hosted rare earth ores and long-term justification for beneficiation and hydrometallurgical upgrades.

    BHP’s iron ore edge: mine planning and product quality lessons for engineers

    BHP chief executive Mike Henry has reaffirmed the company’s iron ore advantage, citing world‑leading EBITDA margins and stronger free cash flow from its Western Australia Iron Ore (WAIO) operations compared with Rio Tinto and Vale. He pointed to sustained low unit costs across BHP’s Pilbara hubs and a high proportion of lump and premium fines products as key drivers of realised price and margin resilience through the cycle. For mine planners and process engineers, the message is continued emphasis on low‑strip orebodies, efficient rail‑port integration and product quality control to defend cost and price premia.

    Greenland Resources’ Malmbjerg moly expansion: exploration and demand lens for mine planners

    Greenland Resources has secured a 1,147.76 km² special exploration licence in the Semersooq region around its existing Malmbjerg molybdenum and magnesium exploitation licence, giving it a dominant mineral tenure position on Greenland’s east coast. Historic geochemistry from the Geological Survey of Denmark and Greenland shows multiple sites with highly anomalous molybdenum values in the new area, and the company plans hyperspectral surveys to refine drill targets and potential resource additions. The move comes as global molybdenum demand is forecast to rise from about 398,000 tonnes in 2024 to 500,000 tonnes per year by 2034.
